Benefits of technology

[0011] In accordance with another aspect of the invention, a sheet material is provided exhibiting an elastic-like behavior in response to elongation forces applied in at least two transverse directions. The sheet material comprises a strainable network having first and second regions formed of substantially the same material composition, the first region providing a first resistive force to the applied e

Problems solved by technology

However, traditional elastics are costly and require a certain degree of manipulation and handling during assembly.
While traditional elastics do provide a degree of stretch for the absorbent article, the materials to which the traditional elastic is secured are typically not normally considered elastic or stretchable.

Embodiment Construction

[0025] Referring to FIG. 1, a web or sheet material 10 illustrating the present invention is shown in which the sheet material 10 is formed with a “strainable network” of distinct regions. As used herein, the term “strainable network” refers to an interconnected and interrelated group of areas which are able to be extended to some useful degree in one direction, preferably a predetermined direction or a plurality of predetermined directions, providing the sheet material 10 with an elastic-like behavior in response to an applied and subsequently released elongation force. The strainable network includes a plurality of first areas 12 that define a first region and a plurality of second areas 14 that define a second region. Portions of the first areas 12, indicated generally as 16, extend in a first direction and are preferably substantially linear. Remaining portions of the first areas 12, indicated generally as 18, extend in a second direction that is substantially perpendicular to t...

Abstract

A sheet material including a strainable network formed in the surface of the sheet material. The strainable network includes first network areas and second network areas, the first network areas substantially surrounding the second network areas. The second network areas include geometrically deformable elements, and the first network areas define substantially unformed portions of the sheet material surrounding the second network areas. The deformable elements are geometrically deformable in plural directions generally parallel to the plane of the sheet material to provide the sheet material with a stretchable elastic-like characteristic in response to elongation forces applied to the sheet material in plural directions.

Description

FIELD OF THE INVENTION [0001] The present invention relates to web materials, and more particularly, to such web materials wherein the inherent elongation properties of a given web material may be modified. Specifically, the present invention relates to web materials in which the resistive force exerted by the web material to an applied elongation in a plurality of directions can be modified. BACKGROUND OF THE INVENTION [0002] Web materials having modified properties to provide a desired resistive force to an applied elongation force on the web are generally known. Such web materials comprise flexible materials useful for forming flexible articles, e.g., flexible bags, which benefit from having a stretchable property facilitating elongation of the web material along a preferential axis of elongation. [0003] Examples of known web materials are disclosed in U.S. Pat. Nos. 5,518,801 (Chappell et al.), 5,650,214 (Anderson et al.), 6,394,651 (Jackson), 6,394,652 (Meyer et al.) and 5,151,...
